  • Change your existing custom tunes on the fly from your Insight CS2 or CTS2
  • Existing Insight CS2 or CTS2 monitor required
  • No additional switches necessary
  • Compatible with EZLYNK or EFI live custom tuning

Instead of modifying your dash to incorporate a switch for switching between performance tunes on your diesel truck, use the EAS Shift-On-The-Fly accessory instead. The EAS SOTF accessory allows your existing Edge Insight CS2 or CTS2 to switch between tunes by using the Edge Accessory Systems hook up, linking the necessary modules and giving you total control for quick switching on the fly. Switching between 5 different tunes has never been easier and can be controlled on the screen of your existing Edge Insight Monitor. Switching occurs by changing voltages between 1v, 2v, 3v, 4v, 5v. Most custom-tuned vehicles run within these parameters. Wire or plug the switch in just as you would your normal Shift-On-The-Fly (SOTF) or Driver-Selectable-Tuning (DST) switch. Then, flash the tune into your vehicle that enables the SOTF/DST functions.
